To all @ii/tom t may conce/mt:

e lie `it known that I, WILLIAM F. VVniGrir, a citizen ot the United States, residing at Qhester, in the county of Delaware andv `etate ot Pennsylvania, have invented new and useful improvements in Hot-h/letal patchcis, of which the following is a spec-llt cation. i

"lhis inventionrelates to hotinetal disi patchers and it" has inorepai'ticular refer` ence to lpneumatic rivet passing apparatus or devices, the 'primary/object being to provide a means which will allow fitor the dis patch of a heated rivet `ronithepoint where it is heated to a remote ordistant location; in other words, that is the locating of the heating apparatus and the dispatcher in the `open for example and dispatching the heated rivettoa remote point such as the interior ot' a ships hull inv order to eliminate gases insaid hull, that would `necessarily be caused by havingthe heating of the rivet therein.` `Furtherrnore iny improvedrivet passing'` apparatus eliminates the use oiinianual passers anddelivers `the heatedrivets to the. place where theyyareto be used `inta properly `heated and good condition. v L further object et this invention is to provide `a rivet passing device of the fore 3o going speciiied character that is simple in `construction,` and `eiiiciein; in operation.`

lV ith the vforegoing and` other objects `in View aswill bemore clearlytapparent from the followingdescription my. invention consists `essentially ol a tank or `chamber which 'forms a standart for the device,` and in this `taulcthere `is provided a coiijipressed air chamber, the operating Vinechanisin being also concealedl within the aforesaid tank.

@duit-ably supported bythe tank is a despatchg nig chamber whichis in cominunicatiou with h the conipressed airchainherand ui'ideiqthe 1ifoiitrol o'l'` a valve normally held closed and operable by the mechanism contained witl'iin the tank, said mechanism being conveniently manually actuated "by `means of a foot treadle` or the like. `The despatching chainber flor` the rivet is:` provided with an opening I normally closed `by a `flap valve, and

through this` opening vthe rivet inserted into said dispatching chamber whence 1t falls bygravity `into a discharge outletgand travelsthrough a helical inetal tube or `the like to the point where it is tobe used under the action ot the compressed air liberated :from the con'iprcssed air chamber when the valve controlling its discharge is tripped or manually opened i. i "In the further disclosure of the invention reference is vto be had to the accompanying sheet of enplanatory drawings constituting` a part of this speciiicat-ionand in which like characters of reference designate the saine or corresponding parts in `both the views.` e Tltgure: l is a top plan `view of iny iin1` proved rivet passing apparatus; and,

. I n s u' Figure 2 is a vertical section taken sul stantiallyon theline2-2 inthe preceding figure.` q1 e f i y Referring t0 the drawings the numeral 3 designates a conical tank whiclrprovides 1a support for and is in communication with a dispatching chamber t into which the rivet is placed and from `which the rivet is dispatched through a metal tube `5, to the de-- sired point, thetankf containing the coinpressed air which is used to impel` the rivet `though said nietal tube 5. `The conical tank `8 is `closed at its lowerend a flanged base plate 6to forma basefor,the/device` fides# ignates a flanged partition spaced from the base plate 6 and secured at its flanged por" tion to the walls of the tank 3 thespace between the said partition 7 and thebase plate `6 forming a compartment for enclosing certain of the operating mechanisms to `be here inafter referred to.v f The upper lend of the tank is closed by acap plate 8 engaging aninwardly extending flange `9v on" the tank `5",

this cap plate 8 is secured tothe liange 9fby any desirable fastening means` suchasthe boltand nut connection-as shown." `Packing may be inserted between the cap plate S and thelange 9 toprevent leakage otconiM peressedfair. The `space between the cap plate "8 and the partition# `forn'is comr pressed air chamber l() having an `inlet 1l j coinmunicatn'ig with a convenient sourceof supply ol? compressed air. e. The cap plate 8 and the partition 7 have `central threaded openings 12, 13 respectively and vinto,.tl1e

opening 12 is` threaded a flanged nipple, '14,

.valve rod.

a valve rod 19, said head 18 being retained in the socket by-a cap 2O having a central opening for the passage therethrough ot said The socket 17 being slightly larger in a vertical direction than the head 18 of the valve rod 19 allows for a retardation in the opening of the valve when the rod 19iS actuated. 421 designates a stutiing box threaded into the threaded opening 13 oi the partition 7, said stutling box 21 having a central opening through which the valve rod 19 passes. 22 designates a central vertical guide sleeve carried by the partition 7 through which the rod 19 passes and is guided.' 23 designates packing held in the stuffing box tojsurround the rod 19 and prevent leakage oli' air past the gland 24 which is held on said packing 23 by the nut 25 threaded into the lower portion ot the stutfing box 21. 26 designates a coilen spring seated on a washer 2? supiviorted on the upper portion of the sleeve 22, the other end oit said spring 26 engaging against a collar 26 fixed tothe rod 19 and thereby exerting an upward pressure which holds the valve 15 supported by the rod 19 in a normally closed position with respect to its seat against the ianged nipple 14. The lowermost end of the rod 19 is provided with a bifurcated portion 28 straddling and pivoted at 29 to a treadle lever 30 which is ulcrumed to a braclret 31 depending from and secured beneath the partition 7, whilst the 'free end ot' the treadle extends through an opening 32 in the VwallA of the tank 3 where it is provided with a foot piece 33. 34 designates a set screw threaded into a bracket 35 located 'below the treadle lever 30, and said set screw 34 is provided with a lock nut 36'for adjustment to limit the downward movement of the treadle lever 30 and thereby control `the lift of the valve 15 with respect to the pressure of the compressed air in the opera tion of the apparatus.

A tubular n'iember or pipe 3T is screwed into the flanged nipple 14 and on the upper end offsaid tubular member 3T is suitably attached the aforesaid t'lispatehing` chamber 4; rTheupper open portion oll the dispatching chamber 4 is closed by a cap plate or cover 38 having a receiving opening 39 tor theinsertion of a rivet'into said dispatching chamber. The receiving opening 39 is normally held closed by an upwardly acting tlap valve 40 seating against the conical seat 41 of the `cap plate 38. This iap valve 40 is pivoted at 42 tothe underside oit the cap plate 38 and it'is provided with an integral bell crank counter-balance 43 which normallyy tends to hold said valve 40 in a closed position with respect to the receiving opening 39. g

Ther receiving opening 39 for the rivet is out of alignnient'with the opening in the tubular member or pipe 37 to prevent a:

rivet when passed therethrough from 'falling into said tubular member or pipe, 3T. The dispatching chamber 4 is provided with an outwardly and downwardly dependingl integral enlargement 44, said enlargement ha ving an opening which communicates into the dispatching chamber 4, Said opening he ing also in communication with the. helical met-al tube 5 ferruled thereon at 45 and held with respect to the enlargement 44 by a nut 4G threaded into a threaded opening in said enlargement.

Ylleierring to Figure it will be clearly seen that the outlet from the valve dispatching chamber is disposed augularly with respect to the rivet receiving opening 1&9 and is substantially in alignment under the said opening` 39 therein7 facilitating the passage ot a rivet into the tube fi. 'lhe use ol' a helical metal tube 5 elliccts the thorough cleansing o1 the rivet lrom scale in its passage therethrough, the action thereot being simi* lar to a rotatable barrel ttor cleaning scale from metal parts. lt will of course bey understood that the tree end ot the tulle 5 is provided with a rivet receiver-not shown on the drawings.

In the use ot the apparatus the same inav be located at a. distance lroni the place where the riveting is to be done, that is to say thc device may be located in the open and the rivets passed thereby to a conlined space such as the hull of a ship where it is desir able to eliminate the gases caused by the heating ot rivets. In the operation oi'` the apparatus a hose communicating with ay source of supply ol eon'ipressed air is coupled to the inlet 11 to supply compressed air into the compressed air compartment 1t). At'ter the rivet is heated the operator inserts the same into the receiving opening- 3th and said rivet by its own weight will cause the lap valve 40 to open and allow said rivet to fall into the dispatching chandler Il, and thence. into the metal tube 5. rlhe tlap valve ,l-t) then` automaticall)v closes under the action ol' its weighted extension or countcrbalance til which as before stated tends to hold the valve in a normally closed position. The. operator presses his toot on the t'oot piece 33 which rocas the treadle :ill downwards and causes the valve rod 19 pivoted thereto to be moved downward iu opposition to the action ot the spring 2t?. 'lhis downward movement ot the rod '19 causes the valve 15 to move away from its scat and thereby allowing` the compressed air in the compartment 1() to pass through the nipple 14, tube or pipe 3T into the dispatching chamber 4, said con'lpressed air impclling the rivet through the tube 5 to the receiver and from which receiver and rivet is taken to be used as and where desired.

From the foregoing description it will be clearlv apparent that b v my invention there llt) lili

" is provided an extremely effective apparatus for the purposes specified, and'whilst there `has been illustrated one practical"embodi-` ment thereof the saine is notto be conserva tively construed as it will be obvious many detail changes may be evolved without departing trom the spirit and scope ofthe invention; `the right is therefore hereby reserved `to malte such changes and modifications as fairly lie within `the scope ofthe appended claims.` f
